It is not my intention to berate anybody's financial situation, but $90 is a pretty paltry sum, especially if you are a skier.
How so, you ask?
Let's see, a large chunk of the resorts out there charge in excess of $65 for a lift ticket. Heck in some spots $65 only gets you a half day!
Let's see, boots run upwards of $700. Skis anywhere from $125 used on up to $1000 new. Bindings anywhere from $100 on up to $300.
Pants = $100 or so
Gloves = $45 and up
Poles = $50 and up
The list goes on (long underwear, wool sweater, socks, hat, gaiters, etc).
Even if you are buying used gear and rocking hand-me-down clothes, you've still gotta scrape the cash together for a lift ticket (unless you're a professional poacher).
My feeling is if you can afford to ski, which most of us seem able to do, then you can easily afford a passport.
Besides, plunking $90 down today will enable you to finally start planning that trip to Kitzbuhl or India or Japan and experience some powder on a global scale!
Give up a day on the slopes and go get that passport, baby!!!
